Details: This poster shows a CH-47D Chinook on the ground. In the background are the first colors of a sunrise.

The Boeing CH-47 Chinook is a versatile, twin-engine, tandem rotor heavy-lift helicopter. Its top speed of 170 knots (196 mph, 315 km/h) was faster than utility and attack helicopters of the 1960s and even many of today. Its primary roles include troop movement, artillery emplacement and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three external-cargo hooks. The Chinook was designed and initially produced by Boeing Vertol in the early 1960s. Chinooks have been sold to 16 nations; the largest users are the U.S. Army and the Royal Air Force. The CH-47D can carry heavy payloads internally and up to 26,000 pounds - for example, bulldozers and large containers - externally, at speeds over 155 mph.
